When the shape is a circle, then the perimeter is called"circumference".The circumference IS the perimeter of a circle.

Circumference of a circle: 2 x pi x radius.

Circumference = (diameter) multiplied by (pi)

Divide the circumference by (2*pi)

If the area of a circle is given as 67cm squared, the diameter is 9.236 cm and the circumference is 29.02 cm

If you mean the diameter and radius of a circle given the circumference it is:- diameter = circumference/pi radius = circumference/(2*pi)

If the circumference or diameter is given then you can find the radius or simply measure the distance from the centre of the circle to the circumference.

Divide the circumference by the value of Pi, then halve that result.
